Assessing the format of the presentation of text in developing a Reading Strategy Assessment Tool (R-SAT)

We are constructing a new computerized test of reading comprehension called the Reading Strategy Assessment Tool (R-SAT). R-SAT elicits and analyzes verbal protocols that readers generate in response to questions as they read texts. We examined whether the amount of information available to the reader when reading and answering questions influenced the extent to which R-SAT accounts for comprehension. We found that R-SAT was most predictive of comprehension when the readers did not have access to the text as they answered questions.     

iSTART 2: Improvements for efficiency and effectiveness

iSTART (interactive strategy training for active reading and thinking) is a Web-based reading strategy trainer that develops students’ ability to self-explain difficult text as a means to improving reading comprehension. Its curriculum consists of modules presented interactively by pedagogical agents: an introduction to the basics of using reading strategies in the context of self-explanation, a demonstration of self-explanation, and a practice module in which the trainee generates self-explanations with feedback on the quality of reading strategies contained in the self-explanations. We discuss the objectives that guided the development of the second version of iSTART toward the goals of increased efficiency for the experimenters and effectiveness in the training. The more pedagogically challenging high school audience is accommodated by (1) a new introduction that increases interactivity, (2) a new demonstration with more and better focused scaffolding, and (3) a new practice module that provides improved feedback and includes a less intense but more extended regimen. Version 2 also benefits experimenters, who can set up and evaluate experiments with less time and effort, because pre- and posttesting has been fully computerized and the process of preparing a text for the practice module has been reduced from more than 1 person-week to about an hour’s time.     

Expressions of positive emotion in photographs,personality, and later-life marital and health outcomes

A previous study of females at an elite liberal arts college found that the degree of positive emotion expressed in persons’ college yearbook photos was correlated with personality, marital, and health outcomes decades later in life. We examine whether the same pattern is observed among respondents in the Wisconsin Longitudinal Study, using high school yearbook photographs and outcome measures obtained mostly when respondents were in their fifties. Despite some seeming advantages of our design, we were unable, with a few exceptions, to replicate the findings of the previous study. Possible explanations for this divergence in findings are discussed, including differences in measurement, the sample, and the photographic occasion itself.     

Relating individual differences in Attitude toward Ambiguity to risky choices

Subjects (76 adult Italians of varying ages) completed a two‐part procedure. One part used an Ellsberg‐type task which allowed for both aggregate and individual level analysis of Attitude toward Ambiguity. The other part used an expanded risky choice task to assess the same subjects' Attitude toward Risk. While there was an overall tendency for subjects to be slightly ambiguity‐averse, there was a positive correlation between Attitude toward Ambiguity and Attitude toward Risk. This relation was particularly strong when the risky choice was to avoid a loss rather than to achieve a gain. Copyright © 2001 John Wiley & Sons, Ltd.
